20090115395 | POWER SUPPLY SYSTEM - A power supply system includes a power supply unit, a conductive wire group and a voltage converter. The conductive wire group consists of a numbers of wires and extends from the power supply unit to electrically connect the voltage converter. The voltage converter can electrically connect at least a working element. Therefore, a first supply voltage is provided from the power supply unit to the voltage converter via the wires, the voltage converter converts the first supply voltage into a second supply voltage for the working element. | 05-07-2009 |
20100066344 | Soft-start circuit - The present invention discloses a soft-start circuit having a reference signal generator, a first current generator, a second current generator, and a soft-start capacitor. The reference signal generator generates a first signal and a second signal. The first current generator generates a first current according to the first signal, and the second current generator generates a second current according to the second signal. The soft-start capacitor is coupled to the first current generator and the second current generator, and charged by a current difference of the first current and the second current to generate a soft-start signal. | 03-18-2010 |
20100066345 | Battery Charger Short Circuit Monitor - Various apparatuses and methods for supplying an electrical current are disclosed herein. For example, some embodiments provide an apparatus including a current regulation switch connected in a current path between a power input and a current output. A current regulator is connected to the current regulation switch. The current regulator includes a current set terminal, and the current through the current regulation switch is proportional to the current through current set terminal. An impedance monitor is connected to the current set terminal. | 03-18-2010 |
20100164472 | POWER SUPPLY MODULATION - Embodiments of methods and apparatus for modulating a power source are disclosed. In some embodiments, a method may comprise predicting, by a current control logic, a potential voltage transient on a power supply bus, and modulating, by the current control logic, a current source, based at least in part on said predicting, to control the predicted voltage transient. Additional variants and embodiments may also be disclosed and claimed. | 07-01-2010 |
20100219805 | APPARATUS AND METHODS FOR BOOSTING ELECTRICAL POWER - An electrical power boosting apparatus includes a metal substrate having a monomolecular carbon-based film on first and second surfaces, a conductive core, a positive electrode at one end, and a negative electrode an opposite end and magnets positioned adjacent and in a spaced-apart relationship to the metal substrate, the magnets are oriented so that north and south poles of each magnet are matched with opposite poles of an adjacent magnet. Electrical power is boosted by passing an initial electric current having an initial voltage through the conductive core of the metal substrate and causing or allowing an interaction between the metal substrate, the monomolecular carbon-based film, and the magnets to produce a modified electric current having a final voltage that is greater than the initial voltage. | 09-02-2010 |
20110254531 | Current Balancing Multiphase Power Converters, Controllers and Methods - A method of controlling a multiphase power converter including a plurality of sub-converters is disclosed. The method includes, for each of the sub-converters, estimating a current provided by that sub-converter. The method includes selecting one of the sub-converters that is on and determined to have a greatest current as the next sub-converter to be turned off and selecting one of the sub-converters that is off and determined to have a smallest current as the next sub-converter to be turned on. Other methods, multiphase power converters and controllers for multiphase power converters are also disclosed. | 10-20-2011 |
